Flooded town, Seidler house heritage-listed

A historic semi-submerged Snowy Mountains town and the family home of the late Sydney architect Harry Seidler are being added to the New South Wales Heritage Register.

Most of Adaminaby was relocated when Lake Eucumbene was flooded in 1957 as part of the construction of the Snowy Hydro Scheme, but parts of the old village and surrounding farmlands have resurfaced because of the low water levels caused by drought.

Lake Eucumbene Chamber of Commerce president Jan Leckstrom says the listing will stop people souveniring important historical relics.

"For the first time ever, the historical remnants of what was once a thriving farming community and small town are forever protected again the marauders who just want to come in and take things for their own private interest," she said.

"They've got to learn you can't take. You can look and admire and you leave behind."

Planning Minister Frank Sartor is also listing a Seidler-designed house built using stone, glass, wood and reinforced concrete at Killara, on Sydney's north shore, in the late 1960s.

Mr Sartor says the house is an outstanding example of modernist architecture.

"It's probably one of the best examples of Harry Seidler's work," he said. "In fact, the Seidler family lived in the home for about 40 years."
